SPECIFICATION forming part of Letters Patent No. 712,521, dated November 4, 1902.

Application filed November 27, 1901. serial .ltn 83,846. (No model.)

To all wit/m1, it 7I'I/(IJ/ con/corn:

Be it known that I, Josnr HENRIK HALL- BERG, a citizen of the Unit-ed States, residing at New York city, county and State of New York, have invented certain new and useful Improvements in Regulators for Alternating Series Arc-Light Systems, of which the following is a specification. r

My invention relates to a device adapted IO to be connected in series with a generator and the arc-lights of an alternating series arelight system, and which has for its purpose to maintain the current on the line constant irrespective of the number of lamps in oper- |5 ation.

The accompanying drawings will serve to illustrate my invention.

Figure l is a view in front elevation of one form of my improved regulator. The view also shows, as a diagram, the regulator connected in series with an alternating generator and a series of arc-lights. Fig. 2 is aview in side elevation, showing a modification of my improved regulator.

In the drawings, A represents an alternating-currentgenerator; l-,a series ofarc-lamps; C, main-line conductor; D, regulator. The regulator consists of the base E, vertical supports F,'and head G, from which is elastically 3o suspended, by means of the springs H, the

magnet-coils I.

The objectof elastically suspending the magnet-coils is for the purpose of permitting a slight downward movement of such coils toward the core when a sudden change of ourrent takes place on the line and which would cause the magnet-coils to attract their core. By this arrangement any distinct pulsation of current on the line owing to a sudden 40 change of current strength is avoided. It will be understood that the magnet-coils will move downward, distending the springs at the same moment or slightly before the core moves upward under the attractive influence 5 of the magnet-coils.

Located under the magnet-coils I, which are connected in series in the main-line cir cuit C, is the core J, formed of laminated iron. The core may be formed with two legs, as shown in Fig. 1, or with four legs, as shown in Fig. The core in each of the figures is counter ialancedin Fig. 1 by means of a weight K and in Fig. 2 by means of the spring K. 'In Fig. 1 the weight K is mounted on theend of a pivoted arm L, upon the opposite end of which is a sector M, to which is connected a flexible strap N, attached at its lower end to the core J. In Fig. 2 one end of the spring K is connected to the head G and the other end to an adjustable bolt 0, secured in a strap I, connected to the lower end of the core J.

Located under the core is a dash-pot- Q and between the dash-pot and the core the spring R. The position of the core J relative to the solenoid I may be adjusted-in Fig. 1 by increasing or decreasing the weight K and in Fig. 2 by increasing or decreasing the tension of the spring K.

The operation of my improved regulator is as follows: hen all the lamps in the circuit are in operation, the position of the core will be that shown in the figures,or,in other words, will be approximately that shown in the figures. When a lamp or lamps are cut out of circuit, the magnets I will attract the core J, and thereby interpose in the circuit an impedance which will be proportional to the resistance of the lamp or lamps cut out of circuit, and vice versa. By reason of the counter weight or spring the regulator may be adusted to'operate the circuit at any given current strength within the capacity of the regulator.

Having thus described my invention, I claim 1. A regulator for alternating series arelight systems, comprising an elastically-suspended magnet-coil in series with the generator and lamps, and a balanced core.

2. A regulator for alternating series arelight systems, comprising an elastically-suspended magnet-coil in series with the generator and lamps, and a balanced and adjustable core.

3. A regulator for alternating series arelight systems, comprising an elastically-suspended magnet-coil in series with the generator and lamps, a balanced core, and a dashpot for dampening the movement of the core.

4. A regulator for alternating series. arelight systems, comprising an elastically-suspended magnet-coil, a balanced core, a dashpot, and an elastic device between the core 5 and the dash-pot.

' 5. A regulator for alternating series arclight systems, comprising a magnet-coil, a balanced core, and means for Varying the resistance of the core against movement.

6. A regulator for alternating series arclight systems, comprising an elastically-suspended solenoidin series with the generator and lamps, a core, and means for counterbalancing the core.

7. A regulator for alternating series arclight systems, comprising an elastically-suspended solenoid in series with the generator and 1amps,a core,means for counterbalancing the core, and means for\ adjusting the core
